Abstract

To provide a stroller with a part of right and left straight pipe parts of a hand bar bent in a U-shape being expandable in the axial direction which is capable of suppressing a play between inner and outer pipes when the right and left straight pipe parts of the hand bar are expanded to the maximum. In the stroller with a part of right and left straight pipe parts of a hand bar bent in a U-shape being constituted of inner and outer double pipes while a small diameter pipe 33 is slidably inserted in a large diameter pipe 34, and expandable in the axial direction, a first inner bush 50 which is fixed to an inner circumferential surface of an opening part at a tip of the large diameter pipe 34 with the small diameter pipe 33 slidably brought into contact therewith, and a second inner bush 51 which is fixed to an outer circumferential surface of a tip of the small diameter pipe 33 and slidably brought into contact with an inner face of the large diameter pipe 34 are provided. When the straight pipe parts are expanded, the inner face of the first inner bush 50 is tightly attached to the small diameter pipe 33, and the second inner bush 51 is tightly attached to the inner face of the large diameter pipe 34 by the interaction of both inner bushes.
